AD5303BRU-REEL

Digital To Analog Converters Overview

The AD5303BRU-REEL is a dual-channel, 8-bit digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.5 V to 5.5 V supply with typical current consumption of 230 μA at 3 V and 300 μA at 5 V. The device features two buffered voltage outputs capable of rail-to-rail swing with a slew rate of 0.7 V/μs. It utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, supporting clock rates up to 30 MHz. Key specifications include ±0.5 LSB integral nonlinearity (INL), guaranteed monotonicity, and power-down modes reducing current to 50 nA at 3 V. The component is housed in a 16-lead TSSOP package.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and reel specifications. Ensure compatibility with system voltage requirements ranging from 2.5 V to 5.5 V. Confirm that the B-version linearity specifications meet the application's accuracy needs before procurement.

Digital To Analog Converters Selection Notes

Select this component for applications requiring dual-channel output in a compact 16-lead TSSOP footprint. The B-version offers tighter linearity (±0.5 LSB INL) compared to the A-version. Consider the external reference configuration options; the BUF pins allow selection between buffered or unbuffered reference inputs depending on source impedance and voltage range requirements.

Digital To Analog Converters Part Context

This part belongs to the AD5303/AD5313/AD5323 family of dual resistor-string DACs. While sharing the same package and interface, the AD5303 is distinguished by its 8-bit resolution, whereas the AD5313 offers 10 bits and the AD5323 provides 12 bits. All variants share similar power characteristics and functional blocks.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include the AD5303ARU-REEL (A-version with ±1 LSB INL). For higher resolution needs, consider the AD5313BRU-REEL (10-bit) or AD5323BRU-REEL (12-bit), noting differences in settling time and linearity specifications.
